Purpose of review: To provide a concise summary of the complete diagnostic and treatment methods to the autoimmune hepatitis, aim to creating a practical handbook for clinicians. Notes: Autoimmune hepatitis (AIH) should be considered in the diagnosis of all adults and children presenting with liver disease symptoms that cannot be explained by other causes such as viral infections or medication-related issues. AIH frequently occurs alongside or coexists with other autoimmune disorders. There are two main types of AIH: Type 1 (AIH-1), more common in adults, and type 2 (AIH-2), which predominantly affects children. A liver biopsy is essential for confirming the diagnosis. Steroid therapy is highly effective and treatment should be tailored to the individual patient. It is crucial not to stop medication prematurely; if the disease is not controlled, treatment should be continued. Typically, AIH treatment lasts for at least two years before considering withdrawal. Even after achieving remission and stopping medication, continuous monitoring is necessary since autoimmune diseases are chronic and may relapse
